Role of Color Doppler Ultrasonography in evaluation of hemodialysis AV fistula

Background : A signi fi cant percentage of the Egyptian population is affected by end-stage kidney disease, which requires long-term hemodialysis. For patients receiving regular hemodialysis, the arteriovenous fi stula is now the method most frequently employed to provide vascular access. Objective : The current study ' s objective was to assess the role and utility of CDUS in assessing vascular access and identifying shunt complications for hemodialysis. Patients and methods : This prospective, randomized controlled trial investigation has been carried out at the Health Insurance Hospital Nasr City ' s radio-diagnosis department. We included a sample size of thirty patients who needed an arteriovenous fi stulain the upperlimb for hemodialysis. Patients rangedin age from8 to70 andwere bothmale andfemale. Results : The majority of patients had normal vessel diameters. 6 patients (20%) have a BB fi stula, 8 patients (26.7%) have an RC fi stula, and 15 patients (50%) have a BC fi stula. The study showed a mean age of AVF maturation occurs 2.17 ± 0.379 weeks after its 1st creation. Three patients had an uncomplicated 10% and 27 patients had shunt complications of 90%. The investigation revealed a signi fi cant percentage of venous thrombosis (12 patients, 40%), stenosis (9 patients, 30%), aneurysmal dilatation (6 patients, 20%), pseudoaneurysmal formation (3 patients, 10%), and fi nally steal syndrome (3.3%, 1 patient). Conclusion : Early identi fi cation and repair of a failing hemodialysis fi stula can improve the quality of hemodialysis treatment. For patients having AV dysfunction, the CDUS results from this series were useful in determining further treatment care.
